Found a well used 1893 Grade B today. It is in 32-40. Both sights are replacements and the receiver had the Hepburn screw holes. The serial number was 383,000 something. The finish was VERY brown and both pieces of wood were repaired and refinished. This would have been a nice Turnbull gun! $695 was the asking price. It was a consignment gun, so the dealer didn't have too much leeway on the price.
